' 'wie Stijehle vicefemi itin 'tijm Enters @mentent uiting tutt at its nime.-

TO' ALL WHOM IT MAY CONOERN Be it known that LIGHABLES C. HOLCOMB, of Mudison, in theicounty of Dune, and State of Wisconsin, have muda new and useful Improvements in Gate und Door-Latches; 'and I do hereby declare the following toi be a. full, eleur, and 'exhct description of the'nu'tui'e, construction, and dperntion of the same, snicient to enableone skilled in the art to which it nppertains to constrlictvnud use th seme, reference bcinghud to the neceinpenyingv drawings, itihicl' are mede part .of this specification, and in which- Figure 1 lisa front elevation of e gate. i Figure 2 ise. viewo'fthe' guard. Figure 3 is a view of the catch. Figure Lis n kside view-of. the latches;`

The inventioneons'istsin combining. togoth er two ln'tehesusdQssprng or. s nringsginsnelto stay .as.,by the op'eraton'o-'Ithe spring, to force theitwo latches asunder at their outer ends, nndthus cause them to slide intov 'their respective catehesa The lstches are pivoted at the back end, F, where they areproyided with eeircular shell, QB, one halt' of which is on each of the latches, A. `The sprinlg, .0, is confined insideef the shell- B, and'is coiled around a short tuhe cast upon the inside of the shell, and in its centre. .'The-envls, C C, of the spring project through the rim of 'the 'shell ageis't e'notch, in which they tak'e-tbeirbeuring,'this cimsingf the latches to open and vrevolve slightly upon the pivot', F, and the 'outer-ends of the latches are thus thrown inte their catches I) D.

Upon compressing tletwolutches A A, untilthey are nearly parallel with euch other, the outer ends of thesame strike against a small pin upon theeatchgplate, theeentre betweenvthe catches, when the gate is readily opened. 4 Y l The great value' of this double latch consists in 'the fectftlint'tlp gatesannot be'ope'ned unless both of the "Seither-'ofitheudrilliseeurelyhold thegate or door shut, when the other is pressedto the centre-pin on the catch-plate. -I'tryli-ll-Iheircsdil-y. seen that unruly nnimaisfcnnnot open this latch.

The gunrdlE is fastened upon the front`ol" the gateor'door, es indicsted in iig; 1,-in such manner as to allow' 'the latches to pass through it, nndis designed to :receive the hl/ow given when the gate is slammed together.

Having described my invention, what I clsimnsneinsnd desire to sec-are by Letters Patent, is Constructinvgthe piveted ends of each latch with u ahell or cup, which, when pnt together, enclose a coil spring operating upen'the latches all together, being suspended `by a. screw or other device, passing through the .centre of the cup and spring and into the gate 'o r dooi', oper igting rind constructed substantially as described-L CHARLES C. IIOLCOMB. l
